Kinetic Light and Mirror Sculpture
This sculpture was conceived and built specially for the 1978 world tour of the renowned pop-music group Genesis. It enabled beams of light to be moved dynamically over the entire Genesis stage, as well as out into the auditorium. It consisted of six very large mirrors mounted in a frame suspended above the stage. Each mirror pivoted on two axes and could be independently rotated in all directions using computer-controlled servomotors. The mirrors reflected beams of light from follow-spot projectors, and during the performance moved about according to a preprogrammed choreography. In certain positions these mirrors also gave the audience reflected aerial views of the musicians.
This sculptural kinetic lighting concept predated the motorised, moveable lighting fixtures that are now the all too ubiquitous feature of most stage shows.
